ELECTRIC PUSH-BUTTON.

SPECIFICATION forming part of Letters Patent No. 580,092, dated April 6, 1897.

Application filed June 30, 1896. Serial No. 597,586. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT L. Moons, a citizen of the United States, residing at Statesville, in the county of Iredell and State of North Carolina, have invented certain new and useful Improvements in Electric Push- Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to electric push-buttons.

Heretofore electric push-buttons, and especially wooden ones, have been constructed of two pieces, one of which carries the contact devices and constitutes a base which is adapted for connection to the wall, and the other a cap which screws onto the base and through which the button works. It not infrequently happens that the cap does not properly screw onto the base, so that it is either too tight and becomes split while being put in position or is so loose that it eventually works out of position. Owing to the fact that the button is constructed in two separate pieces it is rendered more expensive.

My object is to provide a more simple and less expensive electric push-button than the ordinary style and one which will be constructed in a single piece which can be directly connected to the wall or other structure.

The invention consists of an electric push button comprising a cap which carries contact devices of improved construction and novel means connected to the cap and whereby the latter may be connected directly to the wall or other permanent object.

In the accompanying drawings, Figure 1 is a front view of my improved electric pushbutton shown connected to the wall; Fig. 2, a detail rear view of the push-button, and Figs. 3 and 4 sections taken at right angles to each other.

The numeral 1 designates a cap such as is commonly employed, with the exception that it is devoid of the usual screw-thread. The button itself is designated by the numeral 2.

The numeral 3 designates a bent contactspring which acts as a presser-spring for the button. This contact-spring is constructed of a single piece of spring-wire which is bent into a tongue 4, having depressions 5 and humps 6. One portion of the spring is bent into a coil 7 and is then extended and looped around two binding-screws 8 and 9. The tongue is also provided with a bent portion 10, which lies in the coil. One of the wires 11 is connected to binding-post 9.

The numeral 12 designates my improved fastener. This fastener is constructed of a single piece of wire which extends diametrically across the cap, as at 13, so that it will be in alinement with the depressions of the tongue of the contact-spring. The ends of the fastener are bent into eyes 14 and 15, and the extremities 16 and 17 of the fastener are brought back into the push-button, while the numerals 18 and 19 designate screws which pass between the extremities and the body of the fastener and hold the latter firmly in position. The second wire 20 is connected to one of its screws. In putting up a button suitable screws 21 and 22 are placed through the eyes of the fastener and into the wall or other object to which the push-button is to be attached. It will be observed that when the button is pushed inwardly the depressed portion of the fastener of the tongue of the contact-spring is brought against the diametrically-extendin g portion of the fastener and the circuit is completed.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent, is

1. In an electric pushbutton, the combination with a cap of contact devices carried thereby, and fasteners comprising pieces of wire which are bent into eyes and secured to said cap, said fasteners being adapted to receive securing devices.

2. In an electric push-button, the combination with a cap of contact devices carried thereby, pieces of wire bent into the shape of eyes which are extended into shanks, said eyes projecting out from the cap, and screws or equivalent devices passing between the shanks of the eyes into the cap.

3. In an electric push-button, the combination with a cap, of a contact-spring, a button, and a combined contact device and fastener comprising a body which extends across the cap and with which the contact-spring is adapted to make contact, and eyes electrically connected to the body and projecting from the sides of the cap.

4. In an electric push-button, the combi nation with a cap, of a contact-spring, a button, and a combined fastener and contact device comprising a strip of metal which extends diametrically across the cap and is connected Y comprising a single piece of wire having a portion connected to the cap and bent into a free coil, and a spring-tongue which rests against the button, said tongue being adapted for contact with the contact device of the cap.

7. In an electric push-button, the combination with a cap of a contact device connected thereto, a button, and a contact-spring consisting of a single piece of wire having one end connected to the cap and bent into a coil, and an open tongue which rests against the button and having its other end bent and engaging with the coil.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
